I have installed W7 Sp1 on my computer.
Compiled VB6 software - run it on my machine (from Source and exe) and it all works fine.
I then release it to a client running my application on Windows 2000 and nothing works anymore

"VB 6 runtime error 430 - Class does not support automation "

Apparently all access to database classes have changed in W7 SP1 and now I have major problems

Other than reeling back my computer to W7 without Sp1 (which I installed so I could get SQL Server 2012 Running),
What are my options ?

Now this is a good idea, thanks
"One option might be to install the Virtual PC "

I overcame the problem by removing the Service pack 1 (Control Panel, Display Updates, Uninstall Service Pack)
NB: If your machine comes with Service Pack 1 already installed, aparently you cant un-install it

My next test is to install on a Server running SBS 2011 Standard - I will be testing this today
